# Description of the issue

Recently during testing, I cleared my browsing data in Chrome (123.0.6312.124) using their Clear Browsing Data utility.  I cleared data for the last hour.  In doing so, Chrome removed the 'localStorage' object store, but not the 'ngStorage' database from IndexedDB.  When I tried to load my app, I started receiving errors like the following: "Failed to execute 'transaction' on 'IDBDatabase': One of the specified object stores was not found."  I have tested the scenario repeatedly and always get the same result and the 'localStorage' object store is never recreated.

# How to reproduce the issue

1. Allow the Angular app to create some data in IndexedDB
2. Verify that the `ngDatabase` > `localStorage` items are present in IndexedDB
3. In Chrome, use the "Clear Browsing Data" utility to clear browsing data for the last hour
4. Verify that the `ngDatabase` item exists in IndexedDB, but the `localStorage` object store doesn't exist under `ngDatabase`
5. Refresh your Angular app that uses local-storage and you should see the error noted above and the `localStorage` object store is not recreated under `ngDatabase`

Hello @gimmeshelter, thank you for the helpful report which should allow me to reproduce. I will look into it soon and get back to you.

@gimmeshelter I have a few questions:

• what is your OS? (sorry, I did not see you already mentioned that)
• what is your version of Chrome? (sorry, I did not see you already mentioned that)
• which checkbox items are checked and not checked when you do "Clear browsing data"?
• do you have to wait at least one hour has passed to reproduce the issue or not?

Asking these questions because I cannot reproduce on my side: when I clear browsing data in latest Chrome (Version 124.0.6367.62 (Build officiel) (arm64)) on MacOS (so same configuration as you), both the localStorage object store and the ngDatabase database are deleted by Chrome.

@cyrilletuzi I can no longer reproduce this despite reproducing 20x throughout the day yesterday. I am willing to call it a fluke and close.

To answer your questions:

• which checkbox items are checked and not checked when you do "Clear browsing data"?
  • All boxes checked
• do you have to wait at least one hour has passed to reproduce the issue or not?
  • Apparently this does not affect the issue. I left my data from yesterday to today and I cleared browsing data again and both the database and object store were deleted when I cleared browsing data. I can no longer reproduce.

Has your Chrome version changed since? There was the v124 update yesterday/today.

No. During testing today, I was still using 123.0.6312.124. I am in a corporate environment and our updates are centrally controlled, so we're not always on the latest.

I will close the issue for now, because in any cases it would be a browser bug. In indexedDb, object stores can only be created during the database creation or update. So having the object store deleted by the browser but not the database would cause an impossible situation to solve for libraries and applications.

Understood. Thank you for looking into it and I apologize for the false alarm.
